10,000 Simoleons
     At any time during your game (when you are in the house of a Sim)
press  and  hold  [B],  then press [Up], [Left], [Down], then [Right],
then you will hear a chime. You can then release B and within seconds,
the  Cheat Gnome will appear in front of your house near the sidewalk.
You  can  then  select  him  repeatedly  for  10,000  (actually 9,999)
Simoleons each time!

     You  can  then go to grab mode and place him in the inventory, if
desired. No effect, just for fun.
